Xyoo 2019, hauv Lavxias Federation, cov tub ceev xwm tsheb khiav tau tsim ib daim ntawv ntsuam xyuas rau cov neeg tsav tsheb, uas pom tau tias ntau dua 80% ntawm cov neeg tsis paub yuav suav li cas lawv nres qhov deb. Kab lus no tau tsim los kom nkag siab tias yuav ua li cas thiaj suav tau raug.
Pol
Raws li 83% ntawm tag nrho cov neeg tsav tsheb nyob rau hauv Lavxias teb sab Federation tiag tiag tsis paub yuav ua li cas xam lawv cov kev ncua deb ntawm ib tug ceev ntawm 60 km / h. Tus so (17%) muaj peev xwm ua tau. Yog lawm, tej zaum yuav nyuaj. Txawm li cas los xij, kab lus no tau tsim raws nraim rau lub hom phiaj no.
Cov tswv tsheb hauv qhov kev tshawb fawb tau nug los teb ob peb nqe lus nug tshwj xeeb rau cov ncauj lus ntawm kev sib tsoo. Nws yog tsim nyog sau cia tias ntau tshaj 30 txhiab tus neeg tau koom nrog hauv daim ntawv ntsuam xyuas no. Ntawm cov no, 83% ntawm cov neeg teb tsis tau. Qhov tseeb nres deb ntawm 60 km / h yog kwv yees li 45 meters.
Calculation
Yog tias koj mloog cov ntaub ntawv raug cai thiab cov peev txheej, ces lub tsheb nruab nrab thiab tus neeg tsav tsheb ib txwm muaj qhov nruab nrab cov tshuaj tiv thaivnws yuav siv li ob mus rau peb thiab ib nrab vib nas this los ua kom tiav ntawm 60 km / h. Thiab nyob rau lub sijhawm no, tsis yog tsuas yog lub sijhawm ntawm kev nias lub brake pedal nkaus xwb, tab sis kuj muaj cov tshuaj tiv thaiv rau qhov pom ntawm qhov teeb meem, nrog rau kev hloov ntawm koj txhais ko taw los ntawm cov roj pedal mus rau tus nres.
Nyob rau hauv ib ob, lub tsheb ntawm ib tug ceev ntawm 60 kilometers ib teev overcomes 16 meters. Yog li ntawd, yog tias koj ua kom koj lub braking nrug zoo tagnrho, ces nws qhov kev ncua deb yuav yog tsawg kawg yog 45 meters. Txawm li cas los xij, qhov no yog qhov zoo tshaj plaws. Qhov phem tshaj - 55-60.
Fact
Raws li cov kws tshawb fawb, tus neeg tsav tsheb cov tshuaj tiv thaiv rau kev cuam tshuam yog ib thib ob. Lub sijhawm no, lub tsheb ntawm qhov ceev ntawm 60 kilometers ib teev yuav mus txog 16 meters. Lub braking deb ntawm nws tus kheej los ntawm qhov ceev no yuav tsum tau tsawg kawg yog 16 meters (raws li txoj cai ntawm physics). Yog li ntawd, qhov deb tsawg kawg nkaus yuav yog 32 meters. Txawm li cas los xij, kev suav yog ib yam, tab sis kev xyaum yog lwm qhov.
Nyob hauv lub neej txhua hnub hauv cov xwm txheej tiag tiag, nws yuav luag tsis tuaj yeem ua tiav qhov kev sib tsoo zoo li no. Txawm li cas los xij, nws ua tau. Ntxiv mus, tag nrho cov kev suav yog ua nyob rau hauv xws li ib tug txoj kev uas tus neeg tsav tsheb saib ua tib zoo saib ntawm txoj kev thiab ib ncig. Thiab yog tias koj haus luam yeeb thaum muaj xwm txheej ceev, sib tham hauv xov tooj lossis hloov xov tooj cua - qhov no tsis tuaj yeem tham. Nyob rau hauv cov ntaub ntawv no, braking deb yog ib qho tseem ceeb thiab nyob rau hauv ntau zaus koj tsuas yuav tsis nres, los yog koj yuav ua li ntawd tom qab ntaus ib tug neeg.
% piv
50% ntawm tag nrho cov neeg koom nrog kev tshawb fawb teb tias tsuas yog 30 meters xwb thiaj li yuav txaus kom nqa lub tsheb mus rau qhov chaw nres. Txawm li cas los xij, qhov notsis yog lawm, raws li nws tau pom meej hauv cov khoom ntawm kab lus no.
30% hais tias 10 meters txaus. Yog lawm, qhov ntsuas no feem ntau tsis muaj tseeb. Rau lub sijhawm luv luv (tsawg dua li ob, hauv qhov zoo tshaj plaws), tus neeg tsav tsheb tsis muaj sijhawm los teb, cia nyob ib leeg nias lub nres pedal. Peb tsis tau tham txog qhov nres tag. Yog li ntawd, yog tias koj xav txog tiag tiag tias qhov kev ncua deb ntawm 60 kilometers ib teev tsuas yog 10 meters, ces koj xav khob tus neeg kom tuag dua li nres.
Tsuas 10% ntawm tag nrho cov neeg koom nrog kev soj ntsuam teb tias qhov kev ncua deb yuav yog 80 meters. Yog, nyob rau hauv kev xyaum qhov no yog ua tau. Txawm li cas los xij, ntau zaus, cov tsheb tsis zoo, ntawm txoj kev snowy, thiab cov neeg tsav tsheb muaj teeb meem (tsis pom kev, tshuaj tiv thaiv, thiab lwm yam)
Qhov kawg 10% xaiv qhov kev xaiv 45 meter. Nws yog lawv cov uas tseem yog txoj cai - qhov no yog qhov kev ncua deb ntawm qhov ceev ntawm 60 km / h thiab koj yuav tsum nres tag nrho koj lub tsheb. Qhov no yog qhov nws tau pom meej tias yuav ua li cas hauv Lavxias Federation tsav tsheb tsis tuaj yeem suav cov teeb meem lej yooj yim li no.
Ib tug yuav xav tias nws tsis tseem ceeb rau kev tsav tsheb ntawm txoj kev pej xeem. Thiab ib tug neeg xav txawv - yog tias koj tsis paub cov hauv paus, ces koj yuav tsum tsis txhob tsav tsheb. Thiab tseem, cov neeg uas ntseeg tias lub tsheb tuaj yeem ua rau qeeb ntawm 60 km ib teev hauv 10 meters yog qhov tsis raug. Qhov no yuav yog, tab sis tsis nyob rau hauv cov xwm txheej tiag. Tsuas yog hauv kev ua si lossis kev npau suav. Cia qhov kev ncua deb ntawm lub tsheb ntawm qhov ceev ntawm 60 km / h yog 10meters, tab sis tsuas yog nyob rau hauv ib tug mob - yog hais tias koj lub tsheb tsis ua raws li tag nrho cov cai ntawm physics.
Zoo kawg
Kab lus no tau hais txog lub ntsiab lus hais txog lub cev ntawm lub zog ntawm lub tsheb. Nws tau pom tseeb tias qhov lus teb yog li cas hauv qhov kev xaiv tsa uas tub ceev xwm tsheb tau tsim. Thiab qhov tseem ceeb tshaj plaws, cov lus nug tseem ceeb tshaj plaws tau txheeb xyuas hauv cov khoom siv: dab tsi yog qhov braking nrug ntawm qhov ceev ntawm 60 km / h rau lub tsheb.
